Johnson is due to attend one last EU summit on October 17 and 18, which could decide whether Britain leaves the bloc after four decades of membership with or without a divorce deal.
"There will be ample time on both sides of that crucial October 17 summit, ample time in Parliament for MPs to debate the EU, to debate Brexit and all the other issues," he said.
Johnson's announcement came after six opposition parties on Tuesday pledged to prioritise seeking legislative changes to prevent a no-deal Brexit rather than attempting to bring down the government, which has only a single-seat majority in Parliament.
The party's finance spokesman John McDonnell called it a "coup", while Labour former foreign secretary Margaret Beckett said Johnson was "trashing the constitution".
Liberal Democrat Brexit spokesman Tom Brake tweeted: "The mother of all parliaments will not allow him to shut the people's parliament out of the biggest decision facing our country. His declaration of war will be met with an iron fist."
Sarah Wollaston, a former Conservative MP who now sits with the Liberal Democrats, said Johnson was "behaving like a tin pot dictator."
